Joseph Raz's Legal Philosophy
  
   
   
            
   
  I. Introduction 
Joseph Raz emerged in the 1970’s as one of the most influential 
contemporary writers in the philosophy of law. His work in analytical 
legal theory continues a rich tradition running from Thomas Hobbes to 
Jeremy Bentham, John Austin, Hans Kelsen, and H.L.A. Hart. While Raz’s 
views certainly embody a theory of law, he does nothing so simple as 
saying ‘law is.’ Rather, he provides inter-dependent analyses of central
 characteristics of law, usefully approached through his analysis of 
legal norms – the building blocks of legal system – as special kinds of 
practical reasons for action. This central view is explained in section 
II, followed by explanation of his other distinctive contributions to 
legal philosophy. These include an account of the authoritative nature 
of law (section III), a rejection of the legal positivist ‘separation 
thesis’ which nonetheless preserves the positivist insight about the 
moral fallibility of law (section IV), an account of legal system and 
related problems of identity and continuity (section V), and engagement 
with the methodology of legal theory (section VI).  
  II. Legal Norms as Second-Order Reasons 
In early work Raz argues that legal philosophy is best understood as 
one branch of the philosophy of practical reason, philosophy engaged in 
the analysis of reasons for action.(Raz, 1979) Raz distinguishes 
first-order from second-order reasons for action, calling first-order 
reasons those which apply to subjects in the absence of consideration of
 any social institutions or norms. These include, e.g., reasons of 
prudence, health or well-being, and some reasons of morality. 
Second-order reasons are reasons about reasons, and are 
characteristically found where there are social institutions and norms. 
Raz characterizes legal norms as general kinds of 
institutionally-accepted second-order reasons, devoting the most 
attention to mandatory norms, first called ‘exclusionary’ and later 
‘preemptive’ reasons not to act on first-order reasons. A familiar 
non-legal example will illustrate this view. I have a first-order (or 
‘operative’ or ‘dependent’) reason of financial well-being to make sound
 investment decisions, but I am not always in the best physical or 
emotional or rational state to make such decisions. I might then accept 
and practice a second-order reason (i.e., a norm) that I should not make
 any investment decisions when I am tired, no matter how good or bad an 
investment option might look. My second-order reason not to make 
investment decisions when tired here functions to exclude or preempt 
appeal to the first-order reasons (i.e., the merits of an investment 
option and its potential effect on my financial well-being).
Law makes use of second-order reasons in a special way. Where 
norm subjects’ choices in some situation are ordinarily made by relying 
on some one or more first-order reasons for conduct bearing on that 
situation, laws govern that situation by functioning as second-order 
reasons for conduct which exclude or preempt reliance on otherwise 
relevant first-order reasons. For example, we all have first-order 
reasons of safety to coordinate our conduct according to traffic rules. 
 But once a rule has been made, or perhaps crystallized from 
long-standing practice, we no longer need to (nor should in situations 
where we are ignorant of the rules) appeal to first-order reasons of 
safety to determine, e.g, on which side of the road to drive. The legal 
rule, e.g., drive on the right, serves as a second-order or exclusionary
 reason on which we are to act, and so excludes or preempts appeal to 
first-order reasons.  
  III. Law’s Authority 
Raz’s account of the authoritative nature of law is intertwined with 
his account of legal norms. Law’s authority is what gives legal norms 
their legal quality distinguishing them from other second-order norms. 
Raz’s account of law’s authority is perhaps his most distinctive 
contribution to legal philosophy, attracting distinguished advocates, 
and equally distinguished critics.
The theory holds that where law exists, it necessarily claims 
authority to regulate comprehensively, supremely and openly the lives of
 its subjects. (Raz, 1979, 116-120) Law claims to be comprehensive in 
that all aspects of social life are regulated, whether by prohibition, 
requirement, or permission. Law claims to be supreme in that a legal 
system claims to sit at the top of a hierarchy of all normative systems 
and norms within a particular society. Finally, law claims to be open, 
offering support or authorization to various forms of voluntary 
associations and private agreements.
Several aspects of this summary statement deserve further 
explanation.  First, since laws only exist in legal systems, 
investigation of the nature of law is at the same time an investigation 
of legal systems and their authority. Raz notes that since there is 
nothing logically distinctive about legal norms as second-order reasons 
which marks them apart from other, non-legal second-order reasons, what 
makes them legal norms is their membership in a legal system. The 
membership is identified by observation of their systematic application 
by norm-applying institutions. (Raz, 1979, ch. 6)
A second aspect is the special significance Raz’s account 
attaches to law’s self-image. Not only do legal systems provide legal 
norms to guide the conduct of their subjects, they also claim a kind of 
legitimate authority over them. The exclusionary or preemptive reasons 
law provides claim to be justified reasons, since they are meant to 
reflect a settled and accurate view of the first-order reasons which 
apply to subjects.  This aspect of Raz’s view is supported by 
intricately detailed argument, summarized in three distinct theses about
 laws as practical reasons: the dependence thesis, the preemption 
thesis, and the normal justification thesis. (Raz, 1995, 214) The 
dependence thesis maintains that “[a]ll authoritative directives should 
be based, among other factors, on reasons which apply to the subjects of
 those directives and which bear on the circumstances covered by the 
directives.” (Raz, 1995, 214). In other words, law could not claim 
authority unless it claimed to be based, at least in part, on these 
‘dependent’ reasons, which include moral reasons.  The preemption thesis
 holds that law functions to reflect and replace first-order dependent 
reasons, through provision of second-order, preemptive reasons in the 
form of legal norms. In other words, to claim authority is to claim to 
make a practical difference in the practical deliberation of subjects by
 preempting appeal to first-order reasons.  The normal justification 
thesis states that the law claims that subjects are normally justified 
in following law’s directives since to follow these will more likely 
lead subjects to act on the right balance of first-order dependent 
reasons than if subjects tried to act on appeal to first-order dependent
 reasons themselves. 
The dependence, preemption, and normal justification theses which
 constitute Raz’s theory of law’s authority represent a sophisticated 
contribution in political philosophy to understanding the relation 
between subjects and states, and they display Raz’s answer to the 
anarchist’s challenge that authority and reason are incompatible. By 
explaining the nature of law’s authority in terms of its role in 
practical reason, Raz can hold that there is nothing irrational or 
compromising to one’s autonomy in following rules or living under the 
authority of a state. Yet in the philosophy of law the three theses also
 go a long way towards resolution of at least one of the longstanding 
disputes between natural law theorists, who insist that law must be 
understood in terms of its moral purpose, and legal positivists such as 
Hart, who deny any such necessary connection between law and morality.  
On the one hand, Raz’s theory of law’s authority shows that law must be 
understood in terms of its moral purpose: in conceiving of law one must 
understand that necessarily law claims moral authority to settle for 
subjects how they ought to conduct themselves. (Raz, 2003, 14) But, on 
the other hand, by emphasizing the special significance of law’s claim 
for itself to be a moral authority, rather than emphasizing the truth or
 falsity of such a claim in any or all circumstances, Raz’s theory 
preserves the positivist insistence that particular laws and legal 
systems everywhere are morally fallible.
Raz does not, therefore, share Hart’s view of the separation 
thesis which holds that “… it is in no sense a necessary truth that laws
 reproduce or satisfy certain demands of morality, though in fact they 
have often done so.” (Hart, 1994, 185-6) The difference is easy to miss 
but important.  Hart thought that in conceiving of law one need not 
suppose that it must reproduce or satisfy demands of morality: when law 
does reproduce or satisfy demands of morality, it is a matter of 
contingent, historical fact and nothing more. On Raz’s view, in 
conceiving of law one must understand that law claims to be morally 
authoritative, so law must be understood to claim to reproduce or 
satisfy demands of morality. This is of course different from the 
general, external view that it is morally desirable that law reproduce 
or satisfy demands of morality. Rather, the connection is internal: when
 law does reproduce or satisfy demands of morality, we are not 
restricted to the conclusion that this is simply a matter of contingent,
 historical fact. We are also entitled to the observation or conclusion 
that this is part of law’s nature, and that its claim in a particular 
instance happens to be justified. Likewise, when law does not reproduce 
or satisfy demands of morality, we are able to draw the additional 
conclusion that law’s claim, while sincere or genuine, is unjustified.  
(Raz, 2003; see also Green, 2008)
  IV. The Sources Thesis 
While law’s authority is best understood in terms of a moral claim to
 best reflect and replace direct appeal to moral and other first-order 
reasons, Raz emphasizes that legal theorists must not suppose that legal
 directives of states claiming authority are morally legitimate simply 
in virtue of being claimed to be so. Raz’s ‘Sources Thesis’ highlights 
the positivist insistence that the existence of particular laws and 
legal systems is everywhere and always a matter of social practices and 
never a matter of satisfaction of moral principles or values. (Raz, 
1979, 47-52) ‘Exclusive positivism’, as Raz’s view has been called, 
maintains that moral considerations are never among the existence or 
validity conditions of law. (Giudice, 2002, 2003, 2008)
Here we have a second difference between Raz’s and Hart’s view of
 law.  Hart supposed, but defended only briefly, the possibility that 
some legal systems might include or incorporate moral criteria among the
 ultimate tests of legal validity for the membership of legal norms. 
(Hart, 1994, 250) This view has come to be known as ‘inclusive 
positivism’ or ‘incorporationism’, of which there are several variants. 
(Waluchow, 1994; Coleman, 2001; Kramer, 2004) Raz rejects inclusive 
positivism, arguing most forcefully that the possibility of moral 
criteria or considerations counting among the ultimate tests of legal 
validity is incompatible with the claim of authority necessarily made by
 all legal systems.  The ‘argument from authority’ is as follows (Raz, 
1979, ch. 3; 1995, ch. 10). To claim authority, a legal directive must 
at least be capable of claiming authority. To be capable of claiming 
authority a legal directive must purport to make a practical difference 
by excluding or preempting appeal to dependent reasons, which include 
first-order moral reasons.  Inclusive positivism, by maintaining that 
determination of the existence or validity of law might sometimes 
require moral consideration or argument, imagines a situation which 
cannot exist, since to appeal to moral considerations in the 
determination of legal validity renders law incapable of making a 
practical difference, and so renders it incapable of claiming authority 
to settle for subjects what they ought to do according to law.
  V. The Identity and Continuity of Legal Systems  
Raz’s work on the nature of law’s authority continues to develop and 
attract critical attention. But his work in the philosophy of law 
extends far beyond his influential contribution to the theory of law’s 
authority. His work on the nature of legal system offers interesting 
insights and illumination on unresolved problems of identity and 
continuity. Raz famously does not share the view that the identity of 
legal systems – the unified set of member norms – can be solved by 
appeal to a single basic norm or rule of recognition. In his view, there
 could be multiple basic norms or rules of recognition in a single legal
 system. Part of the solution to the problem of identity requires 
observation that legal systems claim to be comprehensive, supreme, and 
open, a view which supposes that legal norms amount to a system when 
they are all operated by the same norm-applying institutions. (Raz, 
1979, chs. 5,6) 
This account, however, is judged even by Raz’s defenders to be 
underdeveloped, facing several problems. In particular, it is far from 
clear that all state legal systems can be accurately understood to be 
making supreme, comprehensive, and open claims to authority.(Marmor, 
2001, 39-42) The idea of legal systems as supreme, comprehensive, and 
open normative systems also leaves intact the problem of the continuity 
of legal systems: what explains the persistence of a legal system and 
what distinguishes changes within a legal system which do not alter its 
identity or existence from changes to a legal system which do alter its 
identity or existence? Raz only offers a theory of momentary legal 
systems, a snapshot in time holding a legal system’s identity and 
existence stable for the purpose of analysis, and suggests that others, 
including Hart, have either overlooked the problem of continuity or 
simply found it unfashionable to solve. (Raz, 2001, 11) As new forms of 
legal order emerge, in the form, for example, of the European Union, 
questions of the identity, existence, and continuity of legal systems 
must be taken up again, and Raz’s work may be a particularly helpful 
point of departure. (See Dickson, 2008) 
  VI. Methodology and Conceptual Analysis   
Raz’s work on the theory of law’s authority and the nature of legal 
systems is systematic and profound. His remarks on the methodology of 
legal theory are less systematic, but no less insightful. His view about
 the goals and success conditions of analytical legal theory in 
particular, and social philosophy in general, is perhaps best stated in a
 passage on authority in The Morality of Freedom. He writes 
Accounts of ‘authority’ attempt a double task. They are part 
of an attempt to make explicit elements of our common traditions: a 
highly prized activity in a culture which values self-awareness. At the 
same time such accounts take a position in the traditional debate about 
the precise connections between that and other concepts. They are 
partisan accounts furthering the cause of certain strands in the common 
tradition, by developing and producing new or newly recast arguments in 
their favour.(Raz, 1986, 63) 
A central aim of philosophy of law is to offer explanations of 
the general concepts of law (and the concept of law itself) which are 
responsive to both citizens’ and theorists’ interests in a way which 
illuminates their self-understanding. As he writes elsewhere, the 
theorist’s goal is to “advance our understanding of society by helping 
us understand how people understand themselves.” (Raz, 1995, 237) 
This is a nuanced view, and one far removed from any belief that 
philosophers of law are in the business of elucidating the meaning or 
definition of particular words. Raz’s view is nonetheless vague in one 
respect: what counts as or what are, exactly, the philosophical 
interests of citizens and theorists? But here the vagueness is 
deliberate, and a decisive strength. As Raz notes in identifying the 
unsolved problems of identity and continuity, the interests of citizens 
and theorists shift, such that some problems might fall in or out of 
fashion. About explanations of the concept of law in general, he writes 
that there are no uniquely correct explanations, but only better or 
worse explanations depending on the concerns addressed (Raz, 2001, 10). 
It might be, for example, that in some era and social situation 
explanation of the nature of authority best responded to questions about
 the nature of law, as citizens and theorists alike were concerned to 
understand the nature of their relation to the state. In another era and
 social situation explanation of the nature of governance might be more 
responsive to concerns about the nature of law, as citizens and 
theorists seek to understand new forms of private regulation and their 
relation to public forms of law in a globalizing world. Similarly, in 
one era attention to the nature of state legal systems might have been 
prominent, but this may also be changing as new forms of non-state legal
 orders seem to be emerging. By highlighting the philosophy of law’s 
responsiveness to contingent practices and shifting interests, Raz’s 
views serve well to characterize its never-ending tasks. 
Yet, responsiveness to contingent practices and shifting 
interests might suggest that Raz’s view is incapable of offering what a 
theory of law should: an explanation of law’s universal and essential 
properties.(Raz, 2005, 324, 328) But here appearances of having 
abandoned legal theory’s goal are deceiving, and show a further way in 
which Raz’s view of the methodology of legal theory is nuanced. The fact
 that explanations of the concept of law are explanations in service of 
particular inquirers’ interests does not preclude holding at the same 
time that law has universal or essential properties. In more recent work
 Raz argues that beginning with an explanation of our concept of law, a 
concept developed largely in the Western world of sovereign states, need
 not inevitably result in a rigidly parochial concept of law. While our 
concept of law is a stable part of a common and shared understanding, it
 is still a “philosophical creation”, designed to aid understanding of 
particular social phenomena by mediating between words or phrases and 
aspects of the world. (Raz, 2005, 324-325) As a “philosophical 
creation”, which is more than a reflection of linguistic usage, that 
creation is influenced by new experience, and as Raz notes, our concept 
of law has in fact been changing to make it “more inclusive and less 
parochial”. (Raz, 2005, 332) In this way, concepts of law are not in 
competition with but instead responsive to shifting interests as, e.g, 
our interest in understanding law may be expanding from its familiar 
context of a singular sovereign state to comparison between dissimilar 
types of states to transnational, international, and global contexts. 
Understanding this complex view nonetheless requires observing a 
distinction Raz draws between the nature of law and the concept of law 
(a distinction Raz argues that earlier theorists, including Hart, 
overlooked). (Raz, 2005, 332) The nature of law is to be a metaphysical 
object having universal and essential properties, while the concept of 
law is a parochial, typically prevailing understanding of law’s nature. 
It is important to note that by this distinction Raz does not aim to 
argue that law really does have universal and essential properties – 
only that those committed to supposing that there is such a thing as the
 nature of law are committed to viewing law as having universal and 
essential properties. Whether there is or is not a ‘nature’ of law 
cannot be assessed from evaluation of ‘our’ or ‘your’ concept of law, 
since explanations of concepts of law are explanations of a particular 
perspective of law’s nature, not explanations of the universal and 
essential properties themselves. In other words, no conclusion either 
way – whether law does or does not have universal or essential 
properties – can be drawn from observation that concepts of law differ 
and are subject to change. There is also, then, on Raz's view, nothing 
objectionable in applying our concept of law to other cultures which do 
not share our concept of law, or do not themselves have a concept of law
 at all. What matters is whether other cultures have social institutions
 which have the nature of law: legal institutions which are subject to 
conceptual explanation. An explanation of a concept of law is a thus 
kind of descriptive-explanatory tool used by inquirers with interests 
and perspectives to explain the world to themselves and others as they 
see it. 
There is one final observation which is important to note and 
rounds out Raz’s view of the methodology of legal theory. The closer a 
concept of law comes to covering or designating successfully all 
instances of law, and so transcending its particular origin, the closer 
explanation of that concept of law comes to explanation of the nature of
 law. As Raz writes, 
Is it not our aim to study the nature of law, rather than our 
culture and its concept of law? Yes and no. We aim to improve our 
understanding of the nature of law. The law is a type of social 
institution, the type which is picked up – designated – by the concept 
of law. Hence in improving our understanding of the nature of law we 
assume an understanding of the concept of law, and improve it.” (Raz, 
2005, 331) 
So while the life of a concept of law might have a parochial 
beginning, through its responsiveness to shifting practices and 
broadening interests and perspectives, it may, eventually, come to 
resemble the kind of philosophical concept of law a general 
jurisprudence or truly general legal theory seeks to accompany in 
explanation of the nature of law.
  VII. Conclusion 
Raz’s work in the philosophy of law ranges broadly, from an account 
of the nature of individual legal norms to a theory of legal system to 
an account of the very aims and methods of legal theory. This short 
introduction has been just that, a short introduction to some of his 
leading ideas, attempting to show the marked differences between his 
views and those of previous theorists in the analytical legal theory 
tradition, views which have already influenced a generation of later 
legal philosophers. Perhaps most importantly, Raz’s views show in equal 
measure distinctive contributions to philosophical theorizing of law and
 motivation for pursuing old questions from new directions.
